4.5A H-Bridge DC Motor Driver Module Using TB6549HQ

The H-Bridge Motor Driver Module Based on TB6549HQ IC from Toshiba, is a full-bridge driver IC for DC motors that uses an LDMOS structure for output transistors. High-efficiency drive is possible through the use of a MOS process with low ON-resistance and a PWM drive system. Four modes, CW, CCW, short brake, and stop, can be selected using IN1 and IN2. Supply input 12V to 30V DC and Maximum Load 4.5Amps.
